CARMEL-BY-THE-SEA, Calif.—Every few years, Porsche holds a big celebration of its racing heritage at the Laguna Seca racetrack in Monterey, California. Called Rennsport Reunion, it’s a big deal, drawing a far bigger attendance than when racing series like IndyCar or IMSA visit. And attendees are a passionate crowd, prepared to wait in line for an hour or more just to visit the official merch store.

Rennsport Reunion 7 took place last week, and it was a special one, as this year is Porsche’s 75th anniversary. Among the cars brought over from the company museum was the very first to ever bear the Porsche name, the prototype 356/1 roadster.

And Porsche let us drive this priceless artifact.
